Now that is what you call customer service! Out of curiosity what is the part number to the ultra high lift blade? I have a few lawns including my own that my 160 and 460 simply will not lift the grass in the tire tracks to cut it cleanly. Our grass is still growing well here for now and I would be willing to buy and try a set before everything slows down in a few weeks.

Its not 355-331 is it? Stens shows 8 blades that are 20.5" long with a 5/8 center hole.

Sorry to take so long getting back to you. It is indeed the 335331. As of now it's cutting cleaner, putting more clippings out that in some cases is enough of a problem that I need to blow them around afterward, and getting more grass collecting under the deck as a result. It's hard to say how much of the change in QOC is due to the set up now or due to my grass drying up and going dormant, along with cutting lower now.
